| 摘 要： | 研究了姬松茸液体种子种龄对其深层发酵过程中生物量、胞内多糖、胞外多糖和胞外纤维素酶的影响 ,以及深层发酵过程中还原糖和 pH值的变化。结果表明 ,种龄为 4d时接种 ,深层发酵产生的生物量、胞内多糖和胞外多糖均高于所选种龄为 6d和 8d时接种 ;种龄为 8d时接种生成的胞外外切 β 1 ,4 葡萄糖苷酶 (C1酶 )与内切 β 1 ,4 葡萄糖苷酶 (Cx酶 )高于种龄为 4d和 6d时接种。

| Abstract: | Insaccharides, the extra cellular polysaccharides, the extra cellular cellulase, the changes of the reduced sugar and pH in submerged fermentation process were studied In this paper the effects of inoculums ages on the growth of mycelium, the cellular polysaccharides production and extra cellular polysaccharides were studied. It is seen that inoculums of cultivation for 4 days were higher than those with inoculums of cultivation for 6 days and 8 days The output of exo 1,4 β D glucanase(enzyme C 1)and endo 1,4 β D glucanase(enzyme Cx)for 8 days were higher than those with inoculums of cultivation for 4 days and 6 days |
